Detailed explanation-1: -El Niño causes the Pacific jet stream to move south and spread further east. During winter, this leads to wetter conditions than usual in the Southern U.S. and warmer and drier conditions in the North.
Detailed explanation-2: -Periods of weaker-or stronger-than-average easterly trade winds initiate El Niño and La Niña. By disrupting the atmospheric circulation in the planet’s largest ocean basin, El Niño shifts the average location and strength of the mid-latitude jet sreams, producing “side effects” on weather around the globe.
Detailed explanation-3: -The term El Niño (Spanish for ‘the Christ Child’) refers to a warming of the ocean surface, or above-average sea surface temperatures, in the central and eastern tropical Pacific Ocean.
